Cobb SF intake,SS, & AP Warranty experiences?

When I pick up my STI the main things that I want to do to it as far as mods goes is the Cobb SF intake with box, the Cobb Short Throw plus bushings, and then us the AP to stage 1 and tune for the SF. I have been through all the warranty threads and read up on it and I know that people have said different things so my question is based on anyone elses actual experiences with talking with service managers/mechanics or have actually taken their cars in, what has been the reaction to these modifications?

I know on my last car (Honda Prelude) I had the warranty from Honda and put a CAI on it and they did not mind. One of the service guys told me that it helped it run cleaner so they had no problem with it. So what are some of the responses you guys have gotten? These are all I really want to do to my STI when I get it just to increase the power a bit and make it run better. Any thoughts?

I think the big thing that a dealer or SOA will look at is not particularly how many mods you have, but rather, the second you hook up a Cobb AP and flash the ECU (even for just an intake), you're changing the entire factory programming of the car. While most people on here would agree that the Subaru factory ECU programming sucks and the Cobb maps (or even a pro-tune map) make the car run much better, smoother and more effeciently, SOA probably won't see it that way.

If I'm not mistaken, the dealer/SOA would have to prove that a modification was the cause of a malfunction. While in and of itself an intake doesn't affect much, flashing the ECU changes everything and is probably enough for SOA to be able to deny warranty coverage if they wanted to. That being said, I've read quite a few threads of people with tons of mods blowing an engine while under warranty, and SOA giving them a one time replacement as a "good grace" kinda thing. In the end it's probably up to the dealer and what kind of info they provide to SOA. I'm sure you'll here both good and bad stories when it comes to this.

Personally, I'm still under warranty and even have an extended warranty on my car. That didn't stop me from some mods. Mainly suspension stuff but I did put on an AEM cold air intake and have the car flashed to Stage 1 + AEM (93 Oct). So far, so good...

Perfect, this is what I was kind of thinking. It makes sense. I am wanting to do the same thing to mine (but with the Cobb SF) simply because I think it can and will make the car perform better and more efficiently as well as make the car funner to drive. I do not want to go too heavy into mods until well after the car is out of warranty but these minor things are simple to install and the benefit they give vs cost is well worth it.

It's very simple, if you go in for a major repair and the modification you have in anyway has anything to do with what is broken expect a denial by subaru. if you loose a ringland bet your ass a SoA rep will come out to check the car out.

Keep in mind, they don't need to prove anything to YOU. Their only legal obligation to you is to provide a denial in writing if you so request. They would need to prove it in a court of law, so unless you are going to sue them all that is nonsense.

100% exactly correct. If you plan to mod plan on having the money saved up if your engine goes.

Since you upped the power Subaru is no longer liable to fix it since it was operating outside of its designed limits. Even if had nothing to due with it they will blame it on it, then it would be up to you to successfully sue a billion dollar company.

What about removing the mods before taking the car in for diagnosis/repair?

For instance, uninstall the Cobb Map and return to stock, remove the Cobb cold air intake and replace stock? These are two relatively minor mods.

I just plan on discussing with the service guys at the dealership where I order my car from. They must realize that these cars people want to add things and these particular mods are quite common. I figure I will be honest with them. I dont plan on adding anything for a few thousand miles but then after that I will want to make these minor upgrades. No point in trying to hide it but I just think they have to realize that people are going to want to do these things especially since for instance the stock map is so inefficient.

I know my dealer is mod friendly. But up to a point. I had a Cobb SF ram intake and they never mention anything about it with my car was consuming oil. They went straight the point after saying my turbo is on the way out.

But then again. My dealer always carries aftermarket parts such Cobb, kartboy, etc.

Just remember, the dealer and SOA can say anything they want. They can deny any warranty claim or make any outlandish assertation that has no basis in reality [e.g. your CAI is why we will not warranty your wheel bearing]. They know that you only have one real recourse; file a law suit against them. The number of people who they piss-off is minimal compared to the customer base and they are more concerned that they do not set a precidence of fixing modified cars for free.

If you are not willing to incur the expense, time, hassel, etc. of a law suit, (and most people are not willing to go that route) then whatever the dealer/SOA says will be what happens.

Wow some of the garbage aka inaccurate information posted in here just astonishes me.

Remember, you better hope that you catch the ring land "on the way out" because if you flash your ecu back to the stock map you still need to drive your car for a little bit to establish parameters on the computer for how you drive. If the tech goes in there and there are no parameters, they will know that you reflashed it. At least this is what I think.

my friend just recently blew up his fully covered stage 2 evo x... before he had the dealer come get it he removed all the parts with the stock parts EXACTLY how it came from the show room... all was fine they checked it over... and he has a new evo...

pretty much as long as you take pictures of everything have have this forum as a reference to go back on when you are taking things apart and putting them back together you should be fine... I am going to stage 1 this weekend on my 2013 Sti so Im in the same boat.

Just Becareful with everything.

Not really true. You lose warranty coverage on your engine, sure. Possibly your tranny if they can prove it, unlikely.

What they are getting at, is if you have no spine and slightly resemble a jelly fish you can return your car to stock and try to lie and get warrant coverage.

dealer has a say to whats been done. it can over look cold shoulder it or if you have parts return it to stock etc. ive had many friends do it PERFECTLY to the point where it came off as it never happened. never an issue with SOA/Warranty

Not always true. If there are mods or any indication there were mods/vehicle returned to stock form, they contact SOA. Could they overlook things? Sure. If they continue to overlook things and turn the blind eye, their warranty per vehicle serviced costs will skyrocket which will result in an audit from SOA which normally results in a mass exodus of certain department personnel(service advisors, service managers, etc). As for engine repairs, if they exceed a certain dollar amount, then they MUST get authorization from SOA. If they do not, then the repair is charged back to the dealer and that will not go over well.

Yeah the customer may not have an issue but over time they will when different faces are there or the same faces start cracking down on things.
